Abstract

본 발명은 아이어닝(ironing) 가공의 경우, 정형명의 끝단에서 돌출되는 버르(burr) 발생을 억제할 수 있는 가공소재를 제공하는 것으로서, 아이어닝 가공이 실행되는 가공소재(21)의 피 아이어닝면(8c,8d)의 단에 아이어닝 가공을 끝내는 아이어닝 펀치(24)의 미끄럼 운동에 따라서 동일 방향에 방생하는 휨(변형)을 피하는 경사면(23a,23b)을 형성하여 단면에 발생하는 버르의 발생의 억제하도록 이루어진 것이다.The present invention is to provide a workpiece that can suppress the occurrence of burrs protruding from the end of the form name in the case of ironing, ironing of the workpiece 21 is ironing Burrs generated on the cross section by forming inclined surfaces 23a and 23b to avoid bending (deformation) occurring in the same direction in accordance with the sliding motion of the ironing punch 24 that finishes ironing at the ends of the surfaces 8c and 8d. It is intended to suppress the occurrence of.
